Two minor bugs:
When you enter a folder with a "\" at the end of the path in the Folder input box, Scud works correctly, but pastes a path with two "\" ("\\") to the clipboard, which of course then doesn't work if you try to access it in Windows Explorer.
When you accidently remove the entry in the Folder input box, Scud still is able to randomly launch a file, but pastes an incomplete path to the clipboard.
